the problem may be the blower control module.it is located under the hood by the blower motor itself,on the right side.it has a wirer connector plugged into it.remove batt connection.then remove module by removing the two small bolts.look at module one of the coil windings will be bad,if so replace module.
You will need to replace the blower motor control unit located inside the blower motor housing, this part is not the same as the part on standard explorers, it is not the same blower motor resistor.
I had the same problem and ended up replacing the blower resistor and the blower motor. Although it could be one or the other .. mine was both.
Climate control blower motor was the fix. The part cost 441 dollars.
If the heat air blower in a 2007 Kia Spectra5 isn't working, it could be due to a blown fuse, a faulty blower motor, or a malfunctioning blower motor resistor. Additionally, issues with the climate control switch or wiring could also prevent the blower from operating. It's advisable to check the fuses first, and if they are intact, further diagnosis of the blower motor and its components may be necessary.
What model? This probably has electronic Climate control,therefore there isn't a Blower resistor. The blower is controlled by a Blower Motor Module...its mounted on the HVAC case under the hood near/next to the blower motor.
The heater blower relay is an electrical component in a vehicle that controls the operation of the blower motor, which circulates air through the heating and ventilation system. When the vehicle's climate control system is activated, the relay receives a signal from the control module and closes the circuit to supply power to the blower motor. This allows the motor to operate at various speeds, adjusting the airflow as needed for heating or cooling the cabin. If the relay fails, the blower motor may not function, leading to inadequate climate control.
Your blower motor relay went bad. You may also need to replace either the blower motor or one of the climate control sensors. If your blower motor squeals or makes a scraping sound it is going bad and will damage the blower motor relay. JQ
The blower motor relay controls the electrical current to the blower motor in a vehicle's heating and air conditioning system. When activated, the relay allows power to flow to the blower motor, enabling it to circulate air inside the cabin. If the relay fails, the blower motor may not operate, leading to issues with climate control within the vehicle. This component is essential for ensuring proper airflow and comfort for passengers.
The AC blower motor on a 1999 Ford Expedition running after the ignition is turned off is typically caused by a faulty blower motor relay or a short circuit in the wiring. Another possibility is a malfunctioning climate control module that may be sending power to the blower motor even when the ignition is off. Additionally, issues with the switch or control panel could lead to unintended operation of the blower motor. It’s advisable to diagnose the electrical system to pinpoint the exact cause.
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.
Depends on the year. You could try the resistor first since it is the cheapest. If not that, then check the fuses, relays and wiring to the control head. Then lastly, change the motor.
